PETER HINKEL, OF ST. LOUIS, MISSOURI.

ELEVATOR.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application filed February 19. 1907- Serial No. 358,305.

To all whom it may concern:

Be it known that I, PETER HINKEL, a citizen of the United States, andresident of St. Louis, Missouri, have invented certain new and usefulImprovements in Elevators, of

which the followin is a specification.

- My invention re ates to improvements in elevators, and has for itsobject to provide a safety device whereby the elevator car will belocked in place Within its shaft in the event ot a breakage of the ropeor cable wherebyflt is normally carried.

In the drawingsFigure 1 is a front plan View of a device embodying myinvention, showing the car in placewithin the vertical guides. Fig.2 isa top plan view of the same, showing the car in place within thevertical guides located in the shaft. Fig. 3 is an end plan view ofthecarrying members in their normal relation to each other; theirabnormal relations which arise from the breakage of the rope or cablebeing indicated in dotted lines. Fig. A is a transverse vertical andlower transverse members bein view in. section of the carrying members,taken along the line 44 of Fig. 1, the upper shown in their abnormalcondition, arising cm the breakage of the rope or cable. Fig. 5 is anenlarged perspective view of those portions of the'locki'n'g deviceembodied in my inven'-- tion which engage with the guides.

- As shown in the drawin s, the device of my invention is interposedctween the main 1 body of the car and the ropes or cables 6 by which thecar is carried.

As. illustrated in Fig. 1, the car 7 is pro- -vided'at its top with atransverse lower carrying member 8, which member serves as a base forthe frame consisting of the parallel uprights 9-9 and 10 10. The leverbars 11,'11 are pivotally'mounted between the uprights 9-9 and 101O atthe points indicated by the numeral 12. At their inner ends, the levers1111 are pivotally connected at the points indicated by the numeral 13to the links1414; the links 14-14 are carried at the extremities of thebar 15, to which the ropesor cables 6 are attached.

The upper transverse member 16 is slidably mountcd'between the uprights!)9 and 10-10, and the sprin 17 is mounted within the uprights 9-9 and1010, and is inter posed between the lower transverse member 8 and theupper transverse member 16. The extremities of the lower transversemember 8 are provided with cross-bars 18 18, the

cross-bars 1Sl8 and the end faces of the member 8 being provided withthe vertical slots 1919, which engage with'the vertical guides 20 withwhich the elevator shaft is provided. The upper transverse member 16 isprovided at its extremities with the castings 2'1-21 which are aperturedas indicatedby the'numeral 22 to accommodate the grips 23. The grips 23are pivotally mounted within the apertures 22 by means of the pivots 24,and at their outer extremities, said grips 23 are pivotally connected atthe points indicated by the numeral 25 with the arms 26, which, in turn,are hinged at the points indicated by the numeral 27 in the cross-bars18-18, which are recessed to receive the arms 26 as indicated by thenumeral 28. It will be observed that by reason of this mode ofconnection between the various parts, that .when the car is in normaloperation and is be- "ing carried by the ropes or cablesfi, the weightof the car causes the variousjparts which have been described to be inthe relative positions shown in Fig. 1. these relative positions, theslots 29 in the castings 21 are open, as indicated in Fig. 3, so thatthe car will slide freely upon the guides 20. In the event of thebreakage of the cables 6, the bar 15 will be relieved of the When inward, as the levers 11 will no. longer exert their downward thrust uponsaid member 16.

*Thereupon, the members 8 and '16 will be forced into the relativeposition indicated in V dotted lines in Fig. 3, and shown in Fig. 4, andthe rounded inner extremities of the grips 23 will be brought togetherby the downward pull exerted through'the arms 26 by the wei ht of thecar, so that they will contact with theside faces of the guide 20 in themanner shown in Figs. 4 and 5; the extent to which the rounded ends ofthe grips 23 will protrudeinto the slot 29 is exaggerated in Fig. 4 forthe purpose of indicating more clearly the mode of operation ofmy'device.

Having fully described my invention, what I claim as new anddcsire tohave secured to me by the grant of Letters Patent, iL.

1. An improvement in elevators comprising a shafta car; guides locatedin the shaft; a plurality ofuprights secured to the top ;of the car; amovable transverse member supported between the uprights; a sprinlocatedbetween the transverse member and the top of the car; leverspivotally mounted in the top of the uprights the one end contacting withthe upper surface'of the transversemember; a bar connected to theopposite ends of the levers and to which is attached the cable; aslotted casting mounted on each end of the transverse member and aplurality of arms and grips carried in the casting, substantially asspecified.

2. A device of the class described comprising an elevator shaft; guideslocated in the -elevator shaft {a car slidably mounted upon the guides;a transverse member movably located upon the top of the car; aspring 10-eated between the transverse member and the top of the car; leverslocated above the transverse member, the outer ends held in depressedposition by the weight of the car; a

plurality of grips and arms plvotally connected together and carried bythe endsof the transverse member and so arranged. as to cause the ripsto contact with the sides of the guides 1n the event the car shouldbecome detached from the cable, specified.

In testimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.
